IMPROVEMENT IN MACHENERY FOR PEEL-WANN@ FLAX.

Specication forming part of Letters Patent No. 55652, dated December 3.9, 1855.

To all lwhom t may concern:

Be it known that I, JIM B. FULLER, of

Claremont, in the county of Sullivan and State 0f NewHampshire, have invented, made, andl lapplied to use a certain new and useful Improvement in the'Preparatiou of -.lilarc and other Fibrous Material and I do hereby declare the following to be a full, clear, and exact de' scription of the said invention, reference bey iug'had to the annexed'drawings, making part of this specicaton, wherein;

Figure 1 is an elevation of the machine em,- ployed by me at the feeding end, part of the screen being removed from the cylinders for more clearly showing them; and Fig. 2 is a longitudinal' section of the machine at right angles to the operating-cylinders.

. Similar letters denote the same parts in both gures. y v .e

lheobject of my inventiony is to free the ber of flax and other vegetable substances of the,

shi ves or hard woody portions that remain with and adhere' to the ber after it has been subjected to a beating, breaking, or crushing operation.

Said invention consists in a series of toothed cylinders and workers that comb out the said ber, in combination with a screen contiguous to thesurface of said cylinders, that retains the fibrous portions andV causes them to pass on from one cylinder to the next without falling away from the teeth of said cylinders. lAt the same time the shives, woody portions, dust, and other foreign matters fall away readily.

In the drawings, a. is a suitable frame-work, .carrying the parts of the machine.

b is a feeding-belt, upon which the ax or other vegetable material is placed, either in its native state or partially prepared.

c c are feeding-rollers, which I prefer to have longitudinal ntes in their surfaces, so as to crack and thoroughly break up the wood y portions and shives. These rollers may be pressed together by weights or springs.

` d is a cylinder armed with teeth conveying the ber from the rollers c to the cylinder c,

which is the rst of a series of working-cylinders, e f g, which maybe multiplied in number, if desired. They are .to be rotated 1n the shives or woody portions and separate t-heA directions indicated by the arrows, and are to c', covered with inclined or card teeth. These vmay be rotated in either direction, but at aconsiderably slower speed than the cylinders ef g, and their teeth pointing toward the ber brought along by the respective cylinders comb oi the ber, so that it is carried along by the stripper It' from the cylindercto the cylinder f, and thence from the cylinder f, by the stripper-, to the cylinder g, and so on.

' I employ screens m n on the opposite sides of the strippers and Workers, curved as shown 1n Fig. 2, so as to stand` contiguous to the surfaces of said cylinders, but not touching the same.

The ber, as carried through the machine, is opened and loosened. by being passed t 'om one cylinder to the next-,and the centril` action of the cylinders c f g throws the ber against the surface of thescreens, and the heavier the vparticles of wood the greater this centrifugal action, the result of which is' that the shives, pieces of woody matter, and other foreign substances are Athrown ont through the sieves. At the same time the operation is great- 1y accelerated by the ber in itspassage moving over and in contact with the rough surfaces of the gratings or screens, which aid in cleansing the ber.

The screens must be sufficiently near tothe respective cylinders to allow the teeth to move the ber along with rapidity and prevent any accumulation oi the ber in a bat against the screens. The ber, having passed a sufficient number of these workers and strippers to be in the desired condition for carding or other- Wise preparing for use, is delivered from the machine by a blower, fan, or other suitable means.

I have shown a cylinder, Z, with smooth radial teeth for throwing the ber off from the cylinder k, and delivering iii over the incline or mouth o.

I prefer that the machin;- sand vertically.,

as shown, to allow the woody portions, dto., to

i'all away with ease from the machine, and a receptacle may be formed, as at p, for the receptfion of such woogy matter; butthe machine combination with a series of strippers and may stand horizontal and the shives all pass workers fitted and acting substantiallyas speci through the bottom screen. fied, and for the purposes set forth.

The cylinders, rollers,&c.,'may be driven at In Witness whereof I have hereunto set my the propery speed by suitable mechanism. I signature this 13th day of June, A. D. 1865.

What I c1am,` and desire to secure by Let# ters Patent, is-,

The grating vor screens contiguous to andxin have shown beltsand pulleys. JIM B. FULLER.
